Seeing as a new rear spring is £130 I decided to go for a Eibach Pro-kit and as luck would have it a m3cutter member had a set which he didn't want, still new in the box £60
Fitted them today without a hitch, car drive a lot better, the ride isn't stupidly firm and the car isn't stupidly low, it just looks as feel right, as if it should have come like this...happy days

Old knackered springs: turns out both rears are screwed lol

New shiny ones

Befores and afters






Will be calling APT to get it booked in for next week, hopefully nothing else will hold it back! Can't wait to get it tweaked to perfect the handling
